The Omron E2B-M30LN20-M1-C2 is an M30 unshielded inductive proximity sensor with a 20 mm sensing distance. Unshielded means it must be mounted non-flush—allow free space around the active face, unlike shielded flush-mount versions. Output is NPN with normally-closed operation, matching sinking inputs on Japanese-origin PLCs. Supply range is 12–24 VDC. The nickel-plated brass body carries an M12 4-pin connector. Overall length is 86 mm, threaded length 51 mm.

Product details
Frequently asked questions
What is the sensing distance and mounting requirement?
Rated 20 mm sensing distance, unshielded design requires non-flush mounting (free space around the face).
What output and operation does this sensor have?
NPN output, normally-closed (NC) operation. Suits sinking PLC inputs and fails safe on wire break.
